查看窃取可见性焦点，当变得可见

Question

在屏幕上，有一个ImageView有焦点。当新视图通过coolNavbarView.setVisiblity(View.GONE)显示时，新视图将会关注焦点。如果用户导航到新视图，则该视图应该能够变得可以聚焦，但是一旦显示它就不应该偷窥焦点。重点应放在已经有焦点的ImageView上。

我知道是一个setFocusable(boolean)方法让视图变得焦点，有没有setStealFocusOnVisible(boolean)方法？

以下是它如何聚焦的堆栈跟踪。

对我而言，ListView是偷窃焦点。我可以通过在使ListView可见之前从ListView中删除Focusable属性来修复它。

ListView v = ViewUtils.findViewById(view, listLayoutId, ListView.class); 
v.setFocusable(false);
